The screen of the display unit 3a is scrolled rightward.

FIG. 8 is a diagram for explaining an internal control operation associated with the operation shown in FIG.

One frame storage unit 12b in RAMI2
Has a storage capacity of, for example, 200 dots vertically × 300 dots horizontally, and stores an image captured by the CCD camera unit 7. However, this one-frame storage unit 12b
Is actually output from the display range coordinate storage unit 12c.
Is data within the range specified by ( ₁ ) (areas indicated by reference symbols R ₁ and R ₂ ), and thus is a part of one frame storage unit 12b cut out.

[0070] Now, when a state of displaying one frame of data storage portion 12b in the region R ₁ is as corresponds to the image shown in FIG. 7 (c), as shown in FIG. 7 (d) , hold down the center key 6s direction instruction key 6, when it is pressing the right arrow key 6a, a central control unit 9, adds the value corresponding to the time that the press that key 6a in the X-coordinate of the region R ₁ than to coordinate the display is changed from the region R ₁ in the region R _2, as a result, the image Fj is moved as shown in FIG. 7 (e),
The addition is stopped when the user releases his / her finger from the right arrow key 6a.

This operation is the same when the other arrow keys 6b to 6d are pressed while the center key 6s is pressed.
That is, when the left arrow key 6c is pressed while the center key 6s is pressed, the central control unit 9 displays
subtracting the X coordinate of the area R ₁ from c to release the finger. When pressing the up arrow key 6d, the user is Y coordinate of the regions R ₁ to release the key 6d is subtracted. When you press the down arrow key 6b is user Y coordinate of the regions R ₁ to release the key 6b is added.

Further, the details of the above operation are described in FIG.
This will be described based on the block diagram of FIG.

First, light is imaged by the lens unit 7a of the CCD camera unit 7, and a subject image is projected on the imaging surface of the CCD 7b. In the CCD 7b, the light projected from the lens unit 7a is converted into an electric signal, and the electric signal is amplified by the amplifier 26.
Output to converter 27. The image signal digitized by the A / D converter 27 is stored in the one-frame storage unit 12b.

When the center key 6s of the direction key 6 is not operated and the switch 23s is OFF, the AND circuit 39
Is opened, whereby the data of the image Fa transmitted from the communication partner taken into the central control unit 9 via the communication circuit 37 is directly shown on the liquid crystal display unit 2a.

On the other hand, when the switch 23s is turned on by operating the center key 6s of the direction indicating key 6, the gate of the AND circuit 38 is opened, whereby the image display range of the image stored in the one frame storage unit 12b is obtained. Coordinate storage unit 34a
In image Fj of the specified range (for example in the range of R ₁ in FIG. 8)
Is output, and the image Fj is displayed on the liquid crystal display unit 2a. That is, as shown in FIG. 7, the display is switched from the image Fa of the other party to the image Fj of oneself.

When the center key 6s of the direction indicating key 6 is pressed to turn on the switch 23s, the pair of gates 29 and 30 are simultaneously opened. At this time, when any one of the arrow keys 6a to 6d is pressed together with the center key 6s, the corresponding switches 23a to 23d are turned on.
Then, this signal is applied to the coordinate adding circuit 28 via the gates 29 and 30. The coordinate adding circuit 28 adds each coordinate by a signal input corresponding to the pressed arrow keys 6a to 6d.
Alternatively, subtraction is performed, and the coordinate value of the calculation result is stored in the image display range coordinate storage unit 34a.

That is, when the right arrow key 6a is pressed together with the center key 6s, "1" is added to the X coordinate, and
When the down arrow key 6b is pressed, "1" is added to the Y coordinate, when the left arrow key 6c is pressed, "1" is subtracted from the X coordinate, and when the up arrow key 6d is pressed, "1" is subtracted from the Y coordinate. Accordingly, as described above, the image Fj displayed on the liquid crystal display unit 2a is moved (see FIG. 7E).

On the other hand, when the center key 6 s is not pressed (when the switch 23 s is OFF), the remaining pair of gates 3
1 and 32 are in an open state. At this time, when one of the up, down, left, and right arrow keys 6a to 6d is pressed,
The corresponding switches 23a to 23d are turned ON, and this signal is applied to the coordinate adding circuit 33 via the gates 31 and 32. The coordinate adding circuit 33 outputs the pressed arrow keys 6a to 6a.
Each coordinate is added or subtracted by a signal input corresponding to 6d, and the value of the coordinate as a result of the calculation is stored in the scroll display range coordinate storage unit 34b.

The display buffer 3 of the liquid crystal display unit 3a
Information of the range indicated by the scroll display range coordinate storage unit 34b is cut out from the image data of the coordinate values stored in 5 and output to the liquid crystal display unit 3a.

FIG. 10 is a plan view showing the input / display section 1a and the fixed keys 1b of the main body cabinet 4.

The fixed key 1b has operation areas for a data selection key 1k, a transmission data confirmation key 1m, a transmission start key 1n, and a temporary file key 1p.

Next, each of the keys 1k, 1m, 1n,
By operating 1p, the information displayed on the input / display unit 1a is moved to the screen of another liquid crystal display unit 3a, or the displayed information is transmitted to the communicating party. The outline will be described.

When the data selection key 1k is first operated during communication with the other party having the same device, all data displayed on the input / display section 1a are to be selected for data processing, and black and white are reversed. Is displayed.

When the transmission data confirmation key 1m is operated in this state, the data displayed on the input / display section 1a is displayed on the liquid crystal display section 3a of the lid 5. When the transmission start key 1n is operated, the data displayed on the input / display section 1a is transmitted to the communication partner.

Further, when information is transmitted to the other party at the same time as the user's own image read by the CCD camera section 7, the transmission speed to the other party should not be extremely reduced.
The user's own image data is 2
The value is converted to a monochrome image, and the image is transmitted with the amount of transmitted information reduced.

Thus, the other party can confirm that the data is being received by changing the received image to black and white display. Furthermore, by returning to the color image at the end of the information reception, it is possible to know that the reception has been completed.

Further, in order to be able to immediately call up frequently used data such as an address book, some data is temporarily stored in the temporary file storage unit 12d by operating the temporary file key 1p. Let it be.

As one method, a screen to be stored is displayed on the input / display section 1a, the data selection key 1k is pressed, and an arbitrary temporary file key 1p is operated in that state. To recall the stored surface data, operate any temporary file key 1p storing the screen data to be recalled,
By operating the data selection key k, the information stored in the temporary file storage unit 12d can be displayed on the input / display unit 1a.

Next, the operation for communicating with the other party by operating the data selection key 1k, the transmission data confirmation key 1m, and the transmission start key 1n will be described in detail.

Normally, data stored in the ROM 11 or the RAM 12 is transmitted to the liquid crystal display 1 c through the central controller 9.
Is displayed on the display buffer 36 and the contents thereof are displayed.

When the data selection key 1k is operated, a signal is sent to a flip-flop (FF) 41, and the FF 41 is set. At this time, the signal “1” from the FF 41 is output to the AND circuit 42. Here, when the transmission start key 1n is operated, this AND
The signal "1" is output to the circuit 42, and the gate 44 is opened by the signal from the AND circuit 42.

The data of the display buffer 36 of the liquid crystal display section 1c is output to the gate 44. When the gate 44 is opened, the data of the display buffer 36 is sent to the communication buffer 45, from which the monochrome circuit is output. A conversion instruction is given to the frame storage unit 1 by the monochrome circuit 46.
Since the image Fj of the user, which is the output content of 2b, is converted to black and white and then output to the central control unit 9, the central control unit 9
Is transmitted from the communication circuit 37 to the communication partner together with the contents of the display buffer 36. When the transmission is completed, the FF 41
Is reset.

When the transmission data confirmation key 1m is operated, a signal "1" is output to the AND circuit 43, and the gate 47 is opened by the signal from the AND circuit 43. At this time, since the data of the display buffer 36 displayed on the input / display unit la is output to the gate 47, this data is sent to the display buffer 35 and displayed on the liquid crystal display unit 3a.

[0094] Next, the data processing will be described with the operation of the temporary file key 1p (1p ₁ ~1p _3).

For example, to temporarily store necessary data in the temporary file storage unit 12d, first operate the data selection unit 1k, and then, for example, the top temporary file key 1p
Operate ₁

When the FF 41 is set by a signal based on the operation of the data selection key 1k, the signal "1" from the FF 41 is commonly supplied to the three AND circuits 48, 49 and 50.

[0097] In this state, then the temporary file key 1p ₁ described above is operated, the signal due to this AND circuit 48
Through the gate 51, the gate 51 is opened.

Since the data of the display buffer 36 storing the data displayed on the input / display section 1a is output to the gate 51, when the gate 51 is opened, the data of the display buffer 36 is output. Is sent to the temporary file storage section 12d of the RAM 12 and the one storage area 12d
Stored in ₁ .

This is because the other temporary file keys 1p ₂ and 1p ₃ are manipulated and the remaining area 12d of the temporary file storage section 12d is operated.
When storing the data in the ₂ to 12d ₃ is the same.

Next, the temporary file storage unit 12 of the RAM 12
If to be read the one storage area data stored in the 12d ₁ example of d is again temporary file key 1
After the operation the p _1, then, to manipulate the data selection key 1k.

[0101] AND in response to the operation of the temporary file key 1p ₁
The signal "1" is output to the circuit 56. At this time, since the data selection key 1k has not been operated yet, the signal "0" has been output from the FF 41. Input, the AND circuit 56
Outputs a signal "1" and sets the FF59.

The AND circuit 62 outputs a signal of "1" to the gate 65 by the output signal "1" from the FF 59 and the signal from the data selection key 1k.
5 is released.
